What effect does music have on you and your studies?

Seeing as this group appears to be suffering from a deathly silence, I will now selflessly attempt to kick-start a conversation!

Stand back I'm going in....

How important is your choice of music on your ability to study? Why do you choose it?
Think focus, concentration, relaxation, energy, motivation and anything else.
Feel free to link to particular tracks, albums, genres or whatever.

My music choices almost always rely on my mood and energy levels. When I'm feeling terrible/frustrated/struggling with study I tend to choose something more ambient or sometimes something upbeat and happy with minimal lyrics.
